Abstract

The invention relates to a short-circuit ring (1) for a rotor (3) of an electrical asynchronous machine. Said short-circuit ring (1) is circular and has across its periphery a plurality of axially extending recesses (13) into which the rods (7) of a rotor cage of the asynchronous machine can be introduced. The short-circuit ring is composed of a plurality of partial ring segments (11).
